CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 399,468, dated March12, 1889.

Application filed June 26, 1888. Serial No. 278,235. (No lllOtlOl- 1b a1071,0111, if 1111/7 (1071,0077):

lie it .known that I, WILLIAM S. G. BAKER, a citizen of the UnitedStates, residing at Baltimore city, in the State of Marylamhhaveinvented certain new and useful Improvements in (ar-illrucks, of whichthe '[i'ollowing is a specification.

1] invention especially relates to the running-gear of the cars of cablerailways.

llcreto'fore the frame for carrying the grip ping mechanism and thewheel. and track brakes of cable-cars have been seen red to the car-bodyor to the axle-liioxes in such manner that it has been difficult toremove the earwheels, axles, and axle-boxes without disconnecting theframes, removing the car-springs, and unnecessarily disarrauging otherparts of the gear. it has also been found diiiicult to organize the gearin such manner that the wear on. the journals shall be equal,and thereshall. be no unequal strain on different parts of the ili'rame.

The object of the first part of my invention is to support the grip andbrake carry ing frames in such manner that the car wheels, axles, andaxle-boxes may be readily removed without taking the car-springs out oftheir suppm'ts or removing the frame from its position under thecar-body.

To this end my invention consists in supporting the frame by means ofbrackets or hangers normally resting on the axle-boxes and provided withseats for the car-springs. In this connection myinvention also consistsin mounting the axle-boxes in pedestals in which the boxes are free tomove vertically, and which are provided at their lower ends withremovable cross bolts or rods beneath the axle-boxes, and in forming thepedestals with seats '11 which the hangers of the gripframes rest whenthe axle-boxes are removed, and. also in certain details ofconstruction, hereinafter explained.

The object of the next part of my invention is to so organize theseveral parts of the gear that the supports for the grip-frame shallrest on the axle-boxes directly over the center of the axle-jourmtls, sothat the wear on the journals shall. be equal, and there shall be nounequal strain of conncciin parts from any sudden jar or verticalnmvcment of the axle-boxes.

To this end my invention consists in providing seats on the axle-boxesdirectly over the j ourna-l-bearings, in supporting the brackets orhangers for the frames in these seats, and in arranging the side beamsof the frames directly under the boxes.

The object of the next part of my invention is to provide an improvedframe for supporting the grip devices and brakes, and in organizing thebrakes to work easily and cffectually.

To this end my invention consists in forming the frame with longitudinalside beams to which cross-beams are secured, and which. are providedwith brackets supported on the axle-boxes. In thisconnection myinvention also consists in mounting the wheel-brakes on the frame andproviding them with operating mechanism of an improved construction, andalso in providing track-brakes having novel operating mechanism.

My invention also consists in certain details of construction and novelorganizations of instrumentalities hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a side view of a car-truckembodying my improvements. Fig. 2 is a side elevation of a part of thetruck, showing some of my improvements more indetail. Fig. 3 is an endview of the same, showing some of the parts in section. Fig. i is a planview of the truck, showing the grip-frame and also in a general way thegrip and brake mechanism. Fig. 5 is a side view of a car-truck, showingmore particularly my improved brake mechanism. Fig. (i is a plan view ofthe same.

The axle-boxes A, Fig. 1, are arranged in pedestals 13, similar ingeneral construction to those shown in. my patent, No. 351-,96l, ofDecember 2S, 1886. The pedestals are bolted to the car-sills C, and arestrengthened by braces l) and D inwell-known ways. T he side beams, C,of the grip-frame are secured to the lower ends of brackets or hangers1*, which extend over the axleboxcs through openings f in the pedestalsand rest in. seats a, formed on the boxes over the center of thejournals. (Sec Figs. 2 and 3.)

The supporting-springs G rest in seats 9 on the brackets 1, and alsoextend into seats 9 in the lateral arms 11 of the pedestals. As

shown in Fig. 3, the bracket F is bifurcated at f, to permit the brace Dto extend through to the pedestal. A bolt, ll, extends through the lowerends of the vertical arms 13 of the pedestal and carries a sleeve, II,which, in connection with the bolt-head h and nut 7L, braces thepedestal at this end. This arrangement also limits the downward movementof the axle-box. When the bolts and sleeves are removed, the axle-boxes,wheels, and axles may be removed from their position in the pedestals.It should be particularly observed that when the axle-boxes, &c., areremoved the grip-frames, their brackets or hangers, and thecar-supporting springs are not materially dislocated, as when theaxle-boxes are out of the way the overhanging end of the brackets dropinto seats f in the openings f in the pedestals B. This is a very simpleand efficient organization, as the axle-boxes, wheels, and axles may bequickly removed by simply raising the ear-body and removing the bolts Hand sleeves H. The life-guard I (shown in Figs. 1 and at) is secured tothe beams E on one or on both ends, as shown in Figs. i and 0.

In Figs. 1 and a I have shown the braces D secured to a frame, J, whichforms part of the truck-frame. The grip-housing K is arranged centrallyin the truck, and is connected to the side beams, E, by cross-rods 7s.The frame J is also braced to the sills O by rods j. Any suitablegrip-operating mechanism may be employed. At each end of the truck, Fig.l, I have shown wheel-brakes L. These brakes are suspended by links Lfrom brackets L on the truck-frame. The links are freely hinged at eachend, and the brakes are connected b y rods Zto an operating-lever, M,and by rod Z to the frame J. The trackbrake N is provided withtoggle-levers O, supported on an uprightplate or frame, P, and connectedwith an operating-lever,P. The details of construction of the brakes andbrake mechanism will not be here further described, as I prefer theorganization shown in Figs. 5 and U of the annexed drawings, to whichreference is now made. The side beams, E, are secured to the brackets Fas above described, and the life-guards I are secured to the side beamsat each end of the truck. Cross-beams Q and Q, extending transverselyacross the truck, are secured to the side beams and carry brackets q, towhich are hinged links (1, that are hinged at their lower ends to thewheel brake-shoes R and R. In this instance the brake -shoes R and Rbear against the inner edges of the wheels.

The brake-shoes on opposite sides of the truck are connected bybrake-beams S, which are provided with inwardly-projecting bolts 8, towhich are hinged togglelevers T, jointed at t and connected by links tto the arms u, secured to a shaft, a, mounted in brackets 10 on thecross-beam Q. The shaft a coin nects the brakes on each side of thetruck, so"

that they act together. The shaft u is provided with anupwardly-extending lever, V, connected by means of a hinged rod, Qf,t0the operating-lever IV, near the center of the car. By operating thelever the brakes may be applied to or withdrawn from all the wheels atpleasure.

To the s ide beams, E, are secured bracketplates X, which are providedwith suitable guides, through which extend the vertical posts X of thetrack-brakes Y. The posts X are firmly secured to each end of the brake,and are screw-threaded at their upper ends to receive adjustable nuts'y, between which and the top of the bracket-plates X are interposedsprings g, which encircle the bolts and tend to lift and normally holdthe brakes away from the trucks. The track-brakes are operated bytoggle-joints formed by levers Z, hinged to the brake-shoes and to thelower ends of the levers Z, which are secured to shafts Z mounted in theup wardly-extending arms x of the brackets X and in bearings .2 in thehousing K.

It will be observed that I provide separate shafts Z insteadrofextending a single shaft across the grip-housing, which constructionwould interfere with the grip mechanism. The shafts Z are connected bymeans of links Z to rock-arms Z" on a shaft, Z mounted in bearings ,2 onthe cross-beam Q. By this arrangement the track-brakes on opposite sidesof the truck are connected so as to be,

operated by a single lever.

The car-truck above described as embodying my invention is simple inconstruction and eflicient in operation. My invention is not, however,limited to the specific details of construction described, as variouschanges may be made without departing from the novel'features of myinvention.
